10kv high voltage cabinet energy storage mechanism principle

The operational principle behind 10kV energy storage revolves around utilizing batteries or other mediums capable of converting electrical energy into stored chemical or potential energy.

Here, we present a topology of a 10 kV high-voltage energy storage PCS without a power frequency transformer for the establishment of a large-scale energy storage system. We analyzed the energy storage converter’s mechanism and characteristics and also introduced the power-control strategy of the HVAC (high-voltage AC) and LVDC (low-voltage .

To generate the HV pulses the main capacitor bank is charged to a voltage at the 10 kV level. Via the semiconductor switch the pulse transformer is connected to the capacitor bank. With the step up ratio of 1:12 the voltage is transformed to the 120 kV level. During the pulse the voltage of the main capacitor droops for about 19 %. The .

We analyzed the energy storage converter’s mechanism and characteristics and also introduced the power-control strategy of the HVAC (high-voltage AC) and LVDC (low-voltage DC) converter.

The main objective of this paper is to design and implement a high voltage (10 kV), high-frequency (50 kHz) center-tapped transformer with high efficiency, small size, and low cost. The proposed transformer is designed as part of a 100 kV, 10 kW DC/DC converter for supplying power to a particle accelerator.
